Troubleshooting & FAQ

What are the signs my carburetor is failing?

Common symptoms include difficulty starting, poor or rough idling, engine stalling at low speeds, black smoke from the exhaust, and visible fuel leaks around the carburetor body.

Is any tuning needed after installation?

This carburetor comes pre-set for the specified Yamaha models. However, minor adjustments to the idle speed or air/fuel mixture screw may be necessary to achieve optimal performance based on your specific engine condition and local altitude.

What is the difference between the 6E0 and 6E3 part numbers?

They are functionally identical and fully interchangeable for the compatible models listed. The different part number series typically represent minor manufacturing updates, regional variations, or revisions over the years, but the core fitment and performance remain the same.

Will this fit my 3HP or 6HP Yamaha model?

No, this carburetor is specifically designed and jetted for Yamaha 4HP and 5HP 2-stroke outboards from 1994–2002. Using it on other horsepower models will likely result in poor engine performance.

Does this assembly include a new mounting gasket?

The package contains the carburetor assembly as pictured. Gaskets are critical for a proper seal and should always be replaced during installation, but they may need to be purchased separately if not shown in the product images.

How often should a carburetor be replaced?

There is no fixed replacement interval. Carburetors are typically replaced only when they show signs of significant wear, internal corrosion, or damage that cannot be resolved by cleaning or using a standard rebuild kit.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

Shipping speed & cost?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

Warranty & returns?

Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.
